I believe that even Vectrix uses this principle on their electric motorbike sized scooter: twist the handlebar grip forward to accelerate, twist backwards to regen and stop. Use the handlebar brake levers if regen is not sufficient. The BMW EVs of a couple years ago had one-pedal-drive in the accelerator. My 1994 US Electricar had this from the beginning where you select the regen level by putting the gear selector in 1,2 or Drive and the Dolphin inverter gets told to either utilize a hard regen, mild regen or light regen. I normally use [1] which gives me hard regen and this allows 1 pedal drive with just the accelerator for all my commute except when there are surprises. As others have said, there are installers of hand-controls to make vehicles suitable for drivers with physical limitations. Cor.
